An arithmetic sequence would have a common difference between successive terms, not the case here.

A geometric sequence has a common ratio; let's check:

\dfrac{1/2}{1/6} = 3

\dfrac{3/2}{1/2} = 3

\dfrac{9/2}{3/2} = 3

That's a common ratio of 3 so as far as we can tell a geometric sequence.

Answer: geometric

For PE Mr Jones wants to split boys and girls equally into as many mixed groups as possible. There are 168 boys and 60 girls. Ho
Bond [772]

Answer:

12

Step-by-step explanation:

You need the greatest common factor of 168 and 60.

168 = 2^3 * 3 * 7

60 = 2^2 * 3 * 5

For the GCF, you need common factors with the lower exponent.

Between 2^3 and 2^2, choose 2^2.

Then you have 3 as a common factor.

5 and seven are not common.

GCF = 2^2 * 3 = 12
